To; all whom it may camera: i

Be it known that Roy H. MCELROY, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, has in-vciited certain new and useful Improvements in Gas-Burners, of which the following is a specification.

This invention relates to new and useful improvements in gas burners of a type adapted to be used in connection with kilns. The primary object of the invention is. to provide a gas burner wliicl1"gives a long flame whereby an even distribution of the heat is secured and the kiln is not damaged from a localization of the heat. Other ob tion on the line 3-3 of Fig. 2; and Fig. 4.

is an end elevation of the burner.

Referring more particularly to the drawings, l represents the side wall of a kiln provided with an arch 2, a bag wall 3 and a burner opening -4i. It is to be understood that the kiln in its entirety comprises a plurality of such portions.

Adapted to extend into the burner opening 4 is the front or discharge end of a burner constructed as follows. The burner consists of an elongated rectangular shell 5- provided at its forward end with a division wall 6-. The wall 6- tapers downwardly and forms an upper passageway 7- which also tapers downwardly, for the air which supports combustion, and a lower passageway -8- for the gas the passage of which is indicated by the arrow, Fig. 2. The shell 5 is provided on its upper side with a thimble -9 which opens into the air passageway '7 and which receives a downtake 1()-- leading from a header 11 supported by brackets 12 on the side of the kiln. The downtake 10 is provided with a suitable valve 13- and receives air under pressure from the header and delivers it to the burner. The under .side of the shell is provided with an openkind of gas.

17 leading from a gas duct -18. The duct 18 leads from a source of fuel such as a gas producer, it, however being unden ing l'% and into th burner is controlled by a sliding valve 22- which lies on the bottom portion of the shell 5 and which is provided with an operating handle 23- extending out through the rear end of the burner. To permit the interior of the burner being cleaned, the rear end thereof is provided with a door 2% hinged at 25 and having a recess 26 which receives the handle 23. The door -24 is also provided with an opening 27, closed by a suitable plug, and which permits access to be had, by means of a scraper, to the valve -22-, whenever the valve becomes obstructed by the tarry deposits of the gas. The shell 5 is also provided with a similar opening 28 which permits access to be had to the uptake 17. The shell is also provided with ears YQ9- with suitable openings by means of which the burner may be elevated and carried to other burner openings of the kiln, it being understood that only enough burners are provided to accommodate those portions or compartments of the kiln being red.

In a gas burner as thus constructed, the gas receives the air for supporting combustion, on top and at a contracted area; consequently, an extended time will be consumed in mixing the gas and air, which results in an elongated flame and'an even distribution of the heat through a large space. Also, the heat is not localized or intensified at any one point, which eliminates deterioration of the kiln and results in a uniform burning of the ware.

Having described my invention, I claim;

1. A removable burner for kilns, com prising an elongated rectangular shell the inner end of which has a downwardly and forwardly slanting air passage within the space of the burner adapted to receive air through the top of the burner, and a gas passage in said burner below the air passage, the said air and gas passages discharging into the burner opening in the wall of the kiln, said burner having a gas inlet in the bottom thereof communicating with the gas passage of the burner, said inlet being in communication with the source of gas supply substantially as described.

2. A removable burner adapted to be con nected into any of the burner openings in the Walls of the kiln, and consisting of an elongated shell the front end of which is adapted to enter the said burner openings, and the central portion of which is adapted to be supported on the gas tunnel masonry, the front end of said burner so entering said burner openings being provided with a downwardly and forwardly slanting air passage extending through the front end of the burner, the said air passage connecting with a down-take through the top of said burner, and a gas passage extending through 'the length of the burner, said gas passage and said a1r passage discharging into the burner openings of the kiln, and the said gas passage connecting through the bottom of the burner with the gas tunnel formed in the masonry of the kiln, substantially as described.

3. A detachable burner for kilns, comprising an elongated rectangular shell having two forwardly and downwardly tapered walls which provide an a1r passage in the top of the burner that discharges through the front end thereof, and a gas passage extending through the length of the burner and also discharging through the front end thereof, said burner having an opening in the bottom thereof through which gas is introduced to the passage through the burner, and means on said burner adapted to facilitate the removal of the burner from one opening in the kiln to another.

In testimony whereof I afiixmy signature.
